meanwhile, the right bevel gear 12 enables the left bevel gear 3 to reversely rotate through the middle bevel gear 7 and the middle bevel gear 8;
the left bevel gear 3 drives the left inner flywheel 4 to rotate reversely, and at the moment, the ratchet pawl inside the left inner flywheel 4 freely rotates in a non-meshing state.
When the right bevel gear 12 rotates anticlockwise under external force, the right bevel gear 12 drives the inner ring of the right inner flywheel 11 to rotate anticlockwise, and at the moment, the ratchet wheel and the pawl inside the right inner flywheel 11 rotate freely without meshing;
